HYDRAULIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 600,173, dated March 8,1898.

' Application filed June 4, 1897. fierial No. 639,416, (No model.)

T0 00% whom it mag concern:

Be it known that I, AARON HOBART S, .a citizen of the UnitedStates,residing at Warwick, in the county of Orange and State of New York, haveinvented certain new and useful Improvements in Hydraulic Motors; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use-the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The special object of the invention is to make an improvement inhydraulic motors which have pivoted and folding buckets.

Figure 1 of the drawings is a median vertical section giving a side viewof the parts; Fig. 2, a vertical cross-section on the dotted line w asof Fig. 1, and Fig. 3 a detail view of the bucket.

In the drawings, A represents the case, B the waste-water-dischargepipe, and O the wheel or disk, whose shaft D is journaled in theopposite plates 1) b. The latter have holes in a circle, so as toregister with the dischargepipe B, for the purpose of carrying off anywater which may have found its way to the space around the shaft.

0 is the pipe, into one end of which the water enters and from the otherend of which it is discharged. This pipe has an enlargement a, in whichthe wheel revolves with its shaft, which may be connected by pulley,spurwheel, or sprocket with any mechanism which is to be operated by themotor.

The disk 0 is provided at suitable intervals on its periphery with thepivoted buckets E and the stops F, the buckets having rear arms e towork against the stops. The buckets E are thus always held at rightangles to the wheel 0 by the stops, while they are folded at the propertime to the wheel by a spring G. By this construction and arrangement ofparts the maximum force of the water is utilized at all times, while thefriction is reduced to a minimum.

What I claim as new is In a hydraulic motor, a discharge-pipe B combinedwith the wheel-shaft and two plates 19 b in the center of which saidshaft has its bearings, one of said plates being provided with a circleof holes which register successively with an open end of said pipe asand for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

AARON BOBARTS.
